NONE - The Geosensing Systems Engineering (GSE) group and the NSF National Center for Airborne Laser Mapping (NCALM) at the University of Houston (UH) has been conducting research, providing education and developing LiDAR hardware and software for the last eight years…Over the last five to ten years, Airborne Laser Swath Mapping (ALSM) technology, also known simply as LiDAR, has become widely available to the remote sensing research community. In that time, many fields of application have been proposed. The majority of the early successful applications were for terrain mapping and surveying, but the high resolution data delivered by this technology has allowed researchers to apply it to many other fields. The UH staffs and researchers will reduce the ALSM data using proprietary software developed by Optech Inc. as well as proprietary software developed by UH researchers. Phase differenced kinematic GPS techniques will be used to process both L1 and L2 GPS signals. KARS software developed by Dr. Gerry Mader, National Geodetic Survey (NGS), National Oceanic and Atmospheric Administration (NOAA) and Applanix POSGNSS will be used to obtain the best GPS track. UH researchers have also developed their own calibration and validation techniques. Each swath of ALSM data is independently processed. Due to the aircraft attitude and motion errors for each swath, overlapping strips generally will not perfectly match to one another. In order to calibrate and compensate for such errors, UH researchers always collect ALSM data with a significant overlap between adjacent swaths. Special calibration and validation techniques are used to adjust the swaths and minimize systematic errors. The Geosensing Imaging and Mapping (GIM) Lab Service Center, University of Houston will deliver data products referenced to either the NAD83 (CORS 96) reference frame or the ITRF00 using a UTM projection in the appropriate zone with units in meters, heights will be either ellipsoidal or NAVD88 as converted by Geoid Model GEOID03. The processing will be performed referenced to GPS base station coordinates tied to the National Network of Continuously Operating Reference Stations (CORS). The navigation data will be processed using both L1 and L2 frequencies and the precise ephemeris (depending on availability), using observations from all available relevant reference stations.
